The Spirit gives life

Our Lord made a covenant with us through baptism in order to give us eternal life. There is in baptism an image both of death and of life, the water being the symbol of death, the Spirit giving the pledge of life. The association of water and the Spirit is explained by the twofold purpose for which baptism was instituted, namely, to destroy the sin in us so that it could never again give birth to death, and to enable us to live by the Spirit and so win the reward of holiness. The water into which the body enters as into a tomb symbolizes death; the Spirit instills into us his life-giving power, awakening our souls from the death of sin to the life that they had in the beginning. This then is what it means to be born again of water and the Spirit: we die in the water, and we come to life again through the Spirit.
To signify this death and to enlighten the baptized by transmitting to them knowledge of God, the great sacrament of baptism is administered by means of a triple immersion and the invocation of each of the three divine Persons. Whatever grace there is in the water comes not from its own nature but from the presence of the Spirit, since baptism is not a cleansing of the body, but a pledge made to God from a clear conscience.
As a preparation for our life after the resurrection, our Lord tells us in the gospel how we should live here and now. He teaches us to be peaceable, long-suffering, undefiled by desire for pleasure, and detached from worldly wealth. In this way we can achieve, by our own free choice, the kind of life that will be natural in the world to come.
Through the Holy Spirit we are restored to paradise, we ascend to the kingdom of heaven, and we are reinstated as adopted sons. Thanks to the Spirit we obtain the right to call God our Father, we become sharers in the grace of Christ, we are called children of light, and we share in everlasting glory. In a word, every blessing is showered upon us, both in this world and in the world to come. As we contemplate them even now, like a reflection in a mirror, it is as though we already possessed the good things our faith tells us that we shall one day enjoy. If this is the pledge, what will the perfection be? If these are the first fruits, what will the full harvest be?

From a homily on the Gospels by Saint Gregory the Great, pope
Christ the good shepherd

I am the good shepherd. I know my own — by which I mean, I love them — and my own know me. In plain words: those who love me are willing to follow me, for anyone who does not love the truth has not yet come to know it.
My dear brethren, you have heard the test we pastors have to undergo. Turn now to consider how these words of our Lord imply a test for yourselves also. Ask yourselves whether you belong to his flock, whether you know him, whether the light of his truth shines in your minds. I assure you that it is not by faith that you will come to know him, but by love; not by mere conviction, but by action. John the evangelist is my authority for this statement. He tells us that anyone who claims to know God without keeping his commandments is a liar.
Consequently, the Lord immediately adds: As the Father knows me and I know the Father; and I lay down my life for my sheep. Clearly he means that laying down his life for his sheep gives evidence of his knowledge of the Father and the Father’s knowledge of him. In other words, by the love with which he dies for his sheep he shows how greatly he loves his Father.
Again he says: My sheep hear my voice, and I know them; they follow me, and I give them eternal life. Shortly before this he had declared: If anyone enters the sheepfold through me he shall be saved; he shall go freely in and out and shall find good pasture. He will enter into a life of faith; from faith he will go out to vision, from belief to contemplation, and will graze in the good pastures of everlasting life.
So our Lord’s sheep will finally reach their grazing ground where all who follow him in simplicity of heart will feed on the green pastures of eternity. These pastures are the spiritual joys of heaven. There the elect look upon the face of God with unclouded vision and feast at the banquet of life for ever more.
Beloved brothers, let us set out for these pastures where we shall keep joyful festival with so many of our fellow citizens. May the thought of their happiness urge us on! Let us stir up our hearts, rekindle our faith, and long eagerly for what heaven has in store for us. To love thus is to be already on our way. No matter what obstacles we encounter, we must not allow them to turn us aside from the joy of that heavenly feast. Anyone who is determined to reach his destination is not deterred by the roughness of the road that leads to it. Nor must we allow the charm of success to seduce us, or we shall be like a foolish traveler who is so distracted by the pleasant meadows through which he is passing that he forgets where he is going.
